Comment 1 for bug 1202479

Hm, on further investigation:

Just to try further, I installed Sheepdog and cinderclient (complianed above), and tried to start glance-api.service:

    $ yum install sheepdog python-cinderclient -y
    $ systemctl start glance-api.service

The service starts successfully:

    $ systemctl status openstack-glance-api.service
